Storage IO Control in vSphere 6.5

What is Storage IO Control?

Storage IO Control is used to control the IO usage of virtual machines and gradually enforce pre-defined shares. Shares can be high, medium or low. This feature was introduced in vSphere 4.1 and requires the Enterprise Plus License.

Step 1: Create a datastore. VMFS was used in this case and a datastore called dy (datastore y) was created.

Step 2: SIOC is now managed via IO Filters Providers. You can easily see the filters are registered automatically. You can select the vCenter server and see these filters.

Step 3: To enable SIOC on a datastore, right click on the datastore and enable SIOC.

Step 4: Next, create a virtual machine policy. Click on Home and select VM Storage Policies to create a new SIOC policy.

Step 5: Name the policy and click on Next.

Step 6: Select SIOC and select High, Medium or Low Shares.

Step 7: Now, apply the policy to the virtual machine. Right click on an existing virtual machine and edit Storage Policies. Select the policy to use and select Apply All.
